Abstract:

The study habits of millennial students are quite different from the students of past times. The new university student generations will need new teaching approaches adapted to their technological skills, with lap tops, tablets, smartphones, and so on, as tools for learning as its own pace, everywhere. In this communication, the adaptation of a collection of study materials, used in an Inorganic Chemistry Foundations topic, for their use in mobile learning and/or BYOD (Bring Your Own Device) strategy is presented. The materials are suited for the understanding of inorganic crystalline solids which, having crystalline structures (long range order), seem so difficult to visualize with 2D figures, as to understand their structural characteristics. The format of these materials was, initially, in pdf documents with 2D figures used for constructing models with little balls, following the steps in the text, on-site class in the laboratory. Later, the use of web pages with Java applets, running with JMol, introduced the students in a 3D visualization of the structure; clicking the different applet buttons students discover the inner structure of the crystalline inorganic solids step by step. Both types of materials have been now brought up to date so that students would use them not only on-site classroom but also in every other time and place. Because JMol with Java doesn’t run in mobile devices, it has been necessary to use JSMol and also re-write the HTML5 (HyperText Markup Language) code and CSS (Cascading Style Sheet) following the RWD (Responsive Web Design) approach. Programming the website to automatically respond to the user’s preferences, it can be switching continuously image size and scripting abilities to accommodate for resolution, depending on the device used.
